Abstract

Selon cette invention, on forme un réseau pour guide d'ondes optique dans un guide d'ondes à diamètre théoriquement uniforme. On modifie une caractéristique du réseau dans des endroits situés le long dudit réseau en proportion sensiblement inverse du diamètre du guide d'ondes dans ces endroits.
